SEALING ATTACHMENT FOR BAGS.

SPECIFICATION forming part of Letters Patent No. 721,926, dated March 3,1903. Appncanon inea :rune 12, 1902. serial No. 111,252. (No man.)

To a/ZZ whom t 7f3/ty concern,.-

Be it known that I, EMIL TYDEN, a citizen of the United States,havingresidence at Hastings,Michigan, have invented certain new and y usefulImprovements in Sealing Attachments for Bags, of which the following isa specification, reference being had to the accompanying drawings,forming a part thereof.

The purpose of this inventionis to provide an improved device forclosing and securing the mouth of a bag and providing in the securingdevice means by which it may be sealed-that is, connected with a sealwhich will have to be broken before the bag-fastening can be released.

It consists in the features of construction which are specified in theclaims.

In the drawings, Figure l is aperspective view of a bag having its mouthclosed by a fastenin g and the fastening secured by a seal, the form ofseal represented beinga familiar form of self-locking strap-seal. Fig. 2is an axial section through the securing device at the line 2 2 on Fig.l. Figf is a section at the line 3 3 on Fig. 2. Fig. t is apartly-sectional detail elevation showing the top portion ofthe bag withsecuring-cord and fastening device, the bag being partly broken away andshown in section at one side.

The bag A has connected to it at the neck` or point at which it is to betied a cord or cable B, which is secured to it vin any desired manner toprevent it from being slipped off over the end of the` bag after it istied, as by the loops C C C, secured on or formed in the bag, orreliance may be placed upon the corded mouth of the bag to prevent thecord from being slipped over the end after it is drawn tight around theneck, or both of these eX- pedients may be employed, as shown in thedrawings. In Whatever manner the seal is secured to the bag or whatevermeans are provided for preventing it from being slipped off over the endof the latter the ends of the cord are passed through the case of thesealing attachment D, being threaded in through one of the holes D' andout through a corresponding holeD2, passing around the wheel E withinthe case and lying in the grooves C C', with which the periphery of thewheel is provided. The wheel, beside being grooved, is serrated, theserrations being preferably ratchet-shapedv that is, with one abrupt andone sloping shoulder, as seen in Fig. 3, the abrupt shoulder beingarranged to face forward in the direction in which the wheel will berotated in passing the cords through the case from the aperture D to theaperture D2-that is, in the direction in which they would be drawn totighten the cord around the neck of the bag, so that the teeth will tendto bite the cord and hold it securely in case any attempt is made todraw it back in a direction to slack the cord at the bag-neck unless thewheel is free to rotate when such attempt is made. The wheel has aplurality of slots F F F F F formed through it from side to side-thatis, in the direction parallel with the axis-these slots being mostconveniently made radial with respect to the axis and spaced from eachother such short distances that the cord may be made tight around themouth of the bag under any circumstances, Vwith the wheel at position atwhich one of the slots registers with the corresponding pair of slots GG in the opposite side walls of theY case. When the cord is thus drawntight on the neck of the bag and a slot of the Wheel is in line with theslots of the case, the seal H, having a strap thrust through the slotsin case and wheel and locked in the manner for which the seal isarranged, it will be seen that thecord cannot be drawn in the directionwhich would rotate the wheelthat is, the directionwhich would slack thecord at the throat of the bag without rupturing the seal-strap-and thisis the purpose sought to be accomplished by the structure.

It will be observed that the tightening might be effected by drawing oneend of the cord only, the other end being fast to the case, and it willbe observed that in fact both ends are fast in the case in the sense andto the extent that they cannot be withdrawn without breaking the seal. Ido not limitmyself to construction in which there are two grooves in thewheel and both cords are drawn for tightening; but either, of the cordsmay be considered as fast in the case, while the other cord is not onlyfast, but adapted to be drawn for tightening the cord.

I claim- 1. A sealing attachment for bags comprising a cord for bindingthe neck of the bag; a

case made fast to one end of the cord; a wheel in the case peripherallygrooved, the case being apertured in its periphery to permit the otherend of the cord to enter and pass around the wheel in the groove thereofand emerge from the case, the Wheel and the case being transverselyapertured to admit a seal when an aperture of the Wheel registers withthose of the case.

2. A bag-sealing attachment comprising a case peripherally apertured forthe cord to enter and emerge therefrom; a wheel in the case around whichthe cord passes within the case, one Wall of the path of the cord beingserrated ratchetwise, the abrupt shoulders of the serrations facingonward in the direction in which the oord must be drawn to tighten it onthe bag; the case having opposite apertures in its side Walls, and theWheel having an aperture adapted to register with the case apertures atone position as the Wheel rotates; whereby a seal-strap may be insertedthrough the apertures of the Wheel and case to prevent reverse rotationof the wheel to slacken the cord.

3. A bag-sealing attachment comprising a cord to close the mouth of thebag; a case peripherally apertured to permit the cord to enter andemerge; a wheel Within the case peripherally grooved and serratedratchetwise, affording lodgment for the cord, the case being closelyfitted around the wheel to cause the cord to be crowded into theserrated groove in passing about the wheel, the abrupt shoulders of theserrations facing onward in the direction in which the Wheel rotates totighten the cord, the case having opposite apertures for the seal-strap,and the Wheel having an aperture that registers with the case-apertureat one position.

4. A bag-sealing attachment comprising a cord for closing the mouth ofthe bag; a case secured to one end of the cord, peripherally aperturedto permit the other end of the cord to enter and emerge; a wheel Withinthe case grooved to aord lodgment for the cord, and around which thecord passes from the entering to the emerging point, the cord beingadapted to fit closely between the periphery of the Wheel and theencompassing Wall of the case, and one of said inclosing elements beingserrated ratchetwise in a direction to resist the slacking of the cord,the case having opposite apertures for a seal-strap, and the Wheelhaving a plurality of apertures adapted to register wit-h thecase-apertures at short intervals in the rotation of the Wheel.

5. A bag-sealing attachment comprising a cord for closing the mouth ofthe bag; a Wheel having two peripheral grooves and a case within whichsuch wheel is inclosed, the case being peripherally apertured to permitthe cord to enter and lodge in the groove of the wheel and emerge afterpassing about the wheel, the grooves and the encompassing Wall of thecase forming a close-fitting path for the cords, the cord-grooves in thewheel being constructed to prevent the cord from slipping on the wheel,the case having opposite apertures adapted to admit a seal-strap, andthe Wheel having a plurality of apertures adapted to register one at atime with said case-apertures as the wheel is revolved in the case.

In testimony whereof I have hereunto set my hand, in the presence of twowitnesses, at Hastings, Michigan, this 7th day of June, 1902.

EMIL TYDEN.
